Double-condensation-box type dryer hopper

Abstract

The invention discloses a double-condensation-box type dryer hopper which comprises a hopper body, a discharging baffle, air duct partition plates and a heat pump compressor. The hopper body is of a hollow structure, a feeding inlet is formed in the top of the hopper body, and a discharging outlet is formed in the bottom of the hopper body. The discharging baffle is arranged in the discharging outlet, and the discharging baffle is connected with the bottom of the hopper body in an inserted mode through manual plug pins. The air duct partition plates are arranged in the hopper body in the direction from the feeding inlet to the discharging outlet. The heat pump compressor is arranged in the hopper body and used for conveying high-temperature and high-pressure refrigerants to condensers. According to the double-condensation-box type dryer hopper, the double condensers are arranged, the heat can be more evenly transferred to dried materials through the double condensers, and therefore various faults and protection caused by the fact that the materials are thick and are not ventilated are greatly reduced, and the service life is greatly prolonged. In addition, due to the heat conduction uniformity of the double condensers, a heat pump system can be located in the optimal operation state with the low pressure all the time, the operation burden of the compressor is reduced, the operation current and the power are reduced, and the design power of a circulating fan can also be reduced.

Description

technical field [0001] The invention relates to the field of hoppers, in particular to a double condensing box type dryer hopper. Background technique [0002] With the popularity of heat pump products in the market, special heat pump dryers are also gradually entering the market, and box dryers have been recognized by many users because of their relatively low price and high energy-saving rate. When the box-type dryer is in use, the heat of the heat pump condenser is transferred to the dried material in the drying hopper by the circulating fan, so as to achieve the purpose of drying. , Publication number is CN212158049U a kind of energy-saving and emission-reducing type filter residue drying device, it all only has a condenser, if material viscosity is bigger when drying, or when there are many materials, it is easy to cause the circulation wind to be unable to penetrate When the circulating air volume becomes smaller, the heat of the heat pump condenser cannot be released...

Problems solved by technology

When the box-type dryer is in use, the heat of the heat pump condenser is transferred to the dried material in the drying hopper by the circulating fan, so as to achieve the purpose of drying. , Publication number is CN212158049U a kind of energy-saving and emission-reducing type filter residue drying device, it all only has a condenser, if material viscosity is bigger when drying, or when there are many materials, it is easy to cause the circulation wind to be unable to penetrate When the circulating air volume becomes smaller, the heat of the heat pump condenser cannot be released due to the reduced circulating air volume, which will cause the pressure of the heat pump refrigerant system to exceed the upper limit, making the operating conditions of the heat pump worse, affecting the service life and drying effect
